10 Best Mini Split Ac Unit For Semi Truck 2026 in the United States

The Mieligo 12V Truck Air Conditioner offers 10,000 BTU cooling power, which is solid for providing comfortable temperatures inside semi-truck cabs and similar vehicles. It uses a DC inverter compressor, which is good for quickly adjusting cooling output and maintaining energy efficiency, helping to save power during use. The system is a split type with separate indoor and outdoor units, making it easier to install in trucks, trailers, and even equipment like cranes or RVs. It runs quietly at about 45 decibels, so it won’t add much noise to your cab environment. The brushless fan improves durability and keeps the noise low, which is helpful during long trips or parking.

A copper evaporator inside ensures efficient cooling, although this part can add to the cost. The unit comes pre-charged with refrigerant, which simplifies installation and avoids extra hassle or expense. You also get remote and panel controls for easy operation, plus an air filter to keep the air inside clean. The system weighs around 70 pounds, which is manageable for installation by professionals. For those concerned about moisture, the unit also helps with dehumidification, keeping the cab comfortable and less sticky.

This AC model is well suited for truck drivers who need reliable, quiet, and efficient cooling during both driving and parking conditions, especially if you want easy installation without extra refrigerant costs.

This 12V DC mini-split air conditioner offers a solid 9000 BTU cooling capacity, which is a good fit for semi-trucks, RVs, and other heavy vehicles needing reliable cooling while parked or on the road. It runs directly off the vehicle’s 12V battery without requiring the engine to be on, helping reduce fuel use and pollution during breaks. The scroll compressor provides efficient and steady cooling performance. Noise is kept low at around 35 decibels, meaning it operates quietly enough not to disturb rest or communication inside the cab.

The unit supports split system installation, which typically means better airflow and easier maintenance compared to window units, but installation may require professional help. A remote control and panel buttons allow easy adjustment of temperature and fan speeds, adding convenience on the go. The unit also has rapid cooling and a 5-level airflow system with 360° rotating outlets for even temperature distribution. On the downside, its energy efficiency rating is modest at 2 stars and a SEER of 13, so it may draw relatively more power compared to higher-efficiency models. It demands a strong vehicle battery—over 200AH—to handle the 60-70 amps current draw, which is important for users to consider to avoid battery drain.

This air conditioner is practical and convenient for truck drivers or RV owners who want a quiet, effective cooling solution powered by their vehicle battery, but it requires attention to power supply and possibly professional installation.

The Aspligo 12V Truck Air Conditioner is a mini-split system designed for semi-trucks and similar vehicles like RVs, excavators, and buses. It offers a cooling capacity of 7200 BTU, which is effective for keeping the cabin comfortable in warm conditions. The unit runs on 12 volts, making it compatible with typical vehicle electrical systems. Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features. This unit is a practical choice for truck drivers or operators seeking reliable cooling with straightforward installation, provided refrigerant charging is appropriately managed.
